They denied the existence of an aether because, if they didn't, it proves the earth does not spin & we can't have that. So instead of admitting this fact they simply removed the proof of it , also, don't hold your breath waiting on Elon Musk.
Musk is well-known for his unrealistic space cruises — in 2011, he promised to put people in space in just three years. Meanwhile, the Falcon Heavy’s launch was originally slated for 2013, then it was moved to 2014 but has again been repeatedly pushed back until "next year".
Just watch and see.
I wish I was wrong, it broke my heart when my blinders came off & I strayed from the herd
What's the benefit of telling people that the earth is flat? What needs to happen for you to see that the earth is a sphere. Who's they? I've done research (not physics research) and there is no motivation to lie to people. Remember that the people doing the research are usually normal people who passed a lot of classes. A lot of thing would not make any sense under the flat earth model. Satellites would not work, the seasons, night and day... etc.
"Passing a lot of classes" to me only means indoctrinated completely. No motivation to lie to people here is one scenerio.
I personally believe there is more land beyond tens or even hundreds of thousands of miles of vast ice plains, until you come upon another localized sun that melts the ice enough to expose more land, and moreland = more resourses which means mass migration leaving the very elite rich to actually fend for themselves and no one to control, but then again.... what do I know.
